PROBLEM TO BE SOLVED: To provide a framework structure, in which complicated connections and joint structures are formed in extremely simple structure, temporary fixing is carried out at the time of execution of works, workability can be improved remarkably while structural strength is increased, the workability of the connections and joints or jointing is enhanced conspicuously and the period of the execution of works can be shortened markedly. SOLUTION: The framework structure has two horizontal structural members 2a, 2b forming beams, girders, purlins, etc., abutted on abutting surfaces at each end section and one or more of bolt inserting hole sections communicated and bored at the angle of inclinationαof 20 deg.<α<90 deg., preferably values from 20 deg.<=α<=70 deg. to 30 deg.<=α<=60 deg. to the abutting surfaces from the outer peripheral wall sections of each horizontal structural member 2a, 2b. The framework structure is formed in constitution, in which one or more of nut seats 4a, 4b cut and formed at the end sections of the bolt inserting hole sections 5a, 5b, 6a, 6b of the outer peripheral wall sections and crossed at right angles with the bolt inserting hole sections 5a, 5b, 6a, 6b, bolts 7a, 7b, 8a, 8b having screw sections at least one end sections inserted into the bolt inserting hole sections 5a, 5b, 6a, 6b, and nuts disposed to the nut seats 4a, 4b and screwed to the screwing sections of the bolts 7a, 7b, 8a, 8b.
